onstruction of National Grid’s new
T-pylon has begun at the company’s
training academy. The building of the
training line of pylons will be the first opportu-
nity to see the new design in the landscape.
The T-pylon was the winner of an interna-
tional design competition to look for a 21st cen-
tury design to carry high voltage overhead lines.
The winning design from Bystrup, the Danish
architects and engineering company, is 35 me-
tres high – up to one third lower than the conventional
steel lattice pylon.
A span of six of the new T-pylons will be built at the
Eakring training academy in Nottinghamshire. The dif-
ferent pylons all have an individual function.
• The standard suspension pylon that is designed to
carry the cables in a straight line. Two suspension
pylons will be built at Eakring.
• A D30 pylon which can allow for the greater pressure
and weight of turning the cables at an angle of up to
• An F10 flying angle suspension pylon which can allow
a turn of up to 10 degrees – the first time such a pylon
has been used in the UK.
• A pair of terminal diamond pylons which end a line
at a substation or take the cables underground.
• A gantry terminal which is an alternative design of
terminal pylon with the same function as the dia-
mond terminal pylon.
David Wright, Director of Electricity Transmission
Asset Management at National Grid said:
“We’ve been able to answer ‘yes’ to the hundreds
OF questions that need to be
asked before we can
introduce a new type of
pylon. The training line has
enabled us to learn so many
lessons about how to
manufacture and build the
T-pylon. I’m incredibly proud
of the high standard of
engineering that brought us
Intended to be more
visually pleasing and less
intrusive on landscape as
well as more economical
and easier to erect.
